HEY GUYS!!, CAN SOMEONE HELP ME WITH THE SIZE OF THE AIRFOIL FOR MY PLANE WINGS AND ALSO AT WHAT ANGLE I SHOULD FIX THE WINGS TO THE BODY OF THE PLANE. I HAVE ATTACHED THE DRAWING FOR THE WINGS.

Check out the airfoil database. Maybe you will get some inspiration.

I am trying to build Boeing 777-200, so if you can give me the size of the airfoils.

My Fuselage is 161.6 cm, body thickness 20.32cm.

my whatsaap number is 9088667788, if you can send me the details or help me in building my project

can you adapt the B737 airfoils to the B777 airfoil ?

WILL THAT WORK, AND IF DO NOT HAVE ANY PROBLEM CAN I HAVE YOUR NUMBER TO DISCUSS A BIT ON THIS PROJECT AS I AM DOING FOR THE SECOND TIME

The Boeing 777, as any other comercial aircraft (and even smaller ones), does not have an exclusive airfoil on its wings. When developing these structures, engineers need to find the best compromise between aerodynamic and structural performance and with that in mind they use several airfoils with different rotations that incredibly increases aerodynamic efficiency. I don't think these big aircraft manufacturers like Airbus or Boeing use NACA or any other known airfoils, instead they work for decades, creating complex geometrical shapes to achieve the best L/D ratio.

Wing loadings do not follow linear scale miniaturization so they need to be much less when building smaller scale models .

So, you building for flight or static ?

@arnab rc,

You might find this of some help.

no i will make it fly

@arnab rc,
Hope you saw the lovely flight and beautiful construction in the first video.

(The crash in the second video was due to incorrect reinstallation of the motor, as explained by the pilot)

Best wishes for your project.
